PLATEN PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 403,365, dated May 14, 1889.

Application filed March 7, 1888. Serial No. 266,410- (No model.)

. art to which it pertains to make and use the same.

My invention relates to improvements in platen printing-presses in which, in addition to mechanism for tilting the platen for handfeeding, provision is made for holding the platen stationary and supplying the paper in rolls, and for automatically feeding the paper from such rolls to the platen and from thence to a cutting device, where the printed matter is severed into sheets and discharged from the machine. The inking-plate is the segment of a hollow cylinder comprising about one-third of a circle, and this plate has an oscillating movement on its axis past the rolls of the ink-fountain, and is overlapped some distance at either throw by the inking-rolls in their oscillations past and some distance beyond the form, the inking-rolls thus being supplied at either end of their stroke with ink, and in turn inking the form while passing once across the latter in either direction.

My invention also relates to details of construction hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation. Figs. 2 and 3 are side elevations, partly in section. Fig. 4: is a plan. Fig. 5 is a rear end elevation with the bed and accompanying parts removed. Fig. 6 is a front end elevation with the platen and connected mechanism removed. Fig. 7 is a rear elevation, in detail, of the shears. Figs. 8 and 9 are side elevations, in detail, hereinafter described. Fig. 10 is an enlarged elevation of details connected with the inking-rolls. Fig. 11 is an enlarged elevation, partly in section, of a portion of lever N and attachments. Fig. 12 is an enlarged detail of the distributing-roller mechanism.

A represents the base, to which is bolted a pair of side frames, A, for supporting the platen D and attachments, driving-shaft F, crank-shaft F, and other mechanism connected directly or indirectly with the platen, feeding device, &c.

A is a frame detachably secured by removable bolts a to base A and frame A. Frame A supports the mechanism for feeding paper from rolls, and is, together with its attachments, removed when the paper is fed by hand.

A is a lateral upright frame that is bolted -to the base and has suitable projecting hubs, a, on which are journaled the supports or arms B of the swinging bed B, and these hubs being hollow form j ournal-bearings for shaft a the axis of this shaft being coincident with the aXis of the hub.

The driving-shaft F is provided, in the usual manner, with fly-wheel, driving and loose pulleys, and crank, provided the press is to be propelled by treadle and foot power, all of which are of ordinary construction, and therefore not shown.

On the driving-shaft are mounted pinions f and f the former engaging gear f of the crank-shaft, and the latter engaging an intermediate gear, f that in turn engages gear A on shaft a the relation of parts being such that the crank-shaft makes two revolutions while gear A makes one revolution.

On the ends of the crank-shaft are mounted disks F having crank-wrists F set in line with each other, to which wrists are attached so-called side bars or pitmen, F for swinging the bed, to which latter the pitmen are pivotally attached. On the crank-shaft, and between the bearings thereof, are mounted cams f f and f. (See Figs. 2 and 3.) Cams f and f are for tilting the platen, and cam is for throwing in and out of gear the feed mechanism hereinafter described, one of the movements (either that of the platen or of the roll-feeding device) being stopped by the removal of parts during the operation of the other movement.

The construction and arrangement of the platen are as follows:

D is a frame located between andrigidly secured to side frames, A, in the inclined position shown in Figs. 1 and 3. On frame D is mounted what might'be called a subplaten or frame, D ,the securing-bolt d passing through rubber block d and passing loosely through holes in frame D and screw-- ing into frame D, with adjusting-screw cl arranged as shown. lVhen once frame D is adjusted, owing to the elasticity of block 01 the slight changes required in the adjustment of frame D to accommodate, for instance, different thicknesses of paper, are made by means of the adjusting-screws without disturbing the securing-bolt d. Frame D is provided with a shoulder, D, for supporting frame D as against a tendency of the latter to slide down the inclined surface of frame D thus relieving the securing-bolts from lateral strain. Boxes D are secured to frame D, and in these boxes are journaled the trunnions D of the platen D. The platen in its depressed position shown in Fig. 1, in which impressions are taken, rests flatwise on frame D. For tilting the platen to the position shown in Fig. 3, in which latter position the sheets of paper are placed thereon by hand, referring to Fig. 3, lever C is pivoted at c to the base A, and is pivoted at c to link C, the latter in turn being pivoted to ears (I of the platen. Lever G is of the bent variety shown, to avoid contact with the driving-shaft. Lever 0 is usually forked at the lower end, only one leg of which is shown, so that the two legs of the lever just fit inside side walls of base A. This, however, is not essential, as a single lever could be rigidly attached to a rock-shaft, with the latter extending from one side frame to the other, which would insure the same steady movement as regards lateral or torsional strain as would accrue from the forked lever shown. Lever G and link 0 form substantially a toggle joint, and the pivotal stud c has mounted thereon roller This rolleris engaged bythe cam f, by which engagement the toggle-joint is moved rearward and brought to the position shown in Fig. 3, whereby the platen is elevated. For moving the toggle-joint forward. to lower the platen, I provide lever 0 pivoted at c to the base. The upper end of this lever has a laterally-proj ecting wrist, on which is j ournaled roller o the latter being engaged by cam f Levers C and C are connected by a strong spiral spring, 0'', by mean a of which the two rollers c and c are held in contact with their respective cams and the toggle-j oint is swayed backward and forward for elevating and depressing the platen.

Link is pivoted to lever C, and bolt C passes through slot O of this link in connecting the latter with lever '1 thus forming a slip-joint at this end of the link. So long as spring (1' performs its functions properly this link remains substantially inoperative; but if from any causesuch, for instance, as tight-fittin g joints, want of proper lubrication, weakening or breaking of spring 0 from long use-link G would operate in place of the spring, or would at least assist the latter. Cams f" and are preferably shaped substantially as shown, whereby the greatest tension of spring 0 is had when most needed in overcoming the inertia of the platen in depressing the latter-a matter of in'iportance when running the press at high speed. Grippers d" are substantially the same as heretofore used, and are removable, being used only with hand-feeding.

The bed-frame aforesaid consists, essentially, of the bed proper, B, on which the form 13 is placed, this bed being rigidly secured to and between supports B. These supports or arms are broad at the top, and are journaled at the bottom, as aforesaid, on hub a. A tie-bar, B of large size, and a still larger tie-bar, 13, pass through lateral holes in the bed 13 and arms 13 with tight fits, the bed, arms, and tie-bars forming a rigid frame-work. One or more tie-rods, B, are provided, connecting the lower portions of arms 13. Bed 13 does not abut arms B, but is separated therefrom some distance, leaving room for the operation of other parts, hereinafter mentioned, from which it will be seen that the bed is supported and held directly and entirely by the two tie-bars aforesaid. Bar ll", outside of arms 1-3, is re duced in size, forming trunnions, on which are respectively 3' ournaled eccentrics Z). These eccentrics are comparatively small in diameter and have little throw, and the rear ends of pitmen F" are bored large enough to fit over these eccentrics. Each eccentric is provided with an ear, Z), to which is pivoted rod b the rods of the two eccentrics being pivoted at their lower ends to short arms Z) of rockshaft 11'. This shaft. passes through lateral holes in arms B, and is journaled therein. A hand-lever, b, is mounted on shaft Z) outside the frame, and extends forward and upward to where it is considered most convenient for the operator. The lever is secured to the shaft by means of a set-screw, so that the d irection of the lever can be changed, raising or lowering the free end thereof, according to the notion of the operator. Only the stub end of this lever is shown. 13y raising the free end of lever If the eccentrics 7) are turned a trifle in the direction that moves the bed rearward to avoid an impression. This part of the mechanism is known as the impres- Sion throw-elf.

A stop of some kind is arranged for lever Z) to rest on in its depressed position. This stop is preferabl y a small eccentric, I)", seen red by a single bolt to the adjacent arm 15. By loosening this bolt the eccentric may be turned to elevate or depress the free end of thelever to bring it where it is most accessible. After such adjustment of the stop and with the other members of the throw-oil in position for taking an impression, the set-screw is tightened that holds lever If on shaft U. The gravity of lever Uholds the impression thro w-o if on, and the operator has only to elevate this lever afewinches in operating the throw-off to avoid an impression. With this arrangement of mechanism by turning eccentric I) a trifle in one direction or the other to elevate or depress lever 1/ (this lever having previously beenadjusted as aforesaid) the eccentrics Z) are turned a trifle to advance or retire the bed, and thus avoid the necessity of manipulating adjuste ing-screws d for thicker or thinner paper. The inking-plate Ecomprises aboutthe one-third of a hollow cylinder. This plate at the end is secured to heads E, the latter being journaled on bar 13*. These heads are cut away, as shown in Fig. 2, in places to avoid contact with shaft G and bar B and are cut away in other places to save metal. Shaft G is journaled in suitable boxes connected with arms B.

J ournaled on bar B next outside of heads E, and fastened to the latter, are segmental gears E for operating the inking-plate. These gears engage similar gears, G the latter being rigidly secured to shaft G. On shaft G, and next outside of gear G are mounted side frames, G, of the inking-rollers, these frames being keyed fast to shaft G. A fractional gear, G is mounted on and keyed fast to shaft G, next outside of one of the roller-frames, and preferably inside the adjacent frame 13, this latter gear engaging a toothed sector, H, Sector H is mounted on shaft H and has a laterally-projecting wrist, H that connects with pitman H for oscillating the sector, by means of which and of the connecting-gears E and G just described, the inking-roller frame and the inking-plates are oscillated in opposite directions, the throw of these members being such that the inking-rollers overlap and travel on the inking-plates some distance at either end of the'throw. In Fig. 2 the inking-plate E and the inking-rollers g are shown at the terminus of the downstroke, and it will be observed that the inking-rollers are in position about midway of the inkingplate, and that the forward edge of the latter is nearthe line of the bed-face. At the termini of the upstrokes the inking-plate is about the same distance from the upper edge of the bed, and the inking-rolls have about the same position midway of the inking-plate, as shown below. The roller-frames G have large openings G to clear cross-bars B and B. These roller-frames have radial slots G and sliding blocks G, operating, respectively, in said slots,

with spiral springs g arranged radially outside the blocks to press the latter inward. One of the inking-rolls is j ournaled at g in levers Figs. 2 and 10, these levers being pivoted at g to block G Levers g are pivoted at g to levers these levers, near their extremes, having holes in which the two remaining rollers g are journaled. By means of the tilting of the levers g and g the inking-rollers are made to conform to the curved surface of the inking-plate and to the flat surface of the form. Springs g are of sufficient tension to give the desired pressure of the inking-rolls upon the form, but are not strong enough to bear up the weight of the inking-rolls and attachments against the inking-plate when the inking mechanism is in the position shown in Fig. 2. To accomplish this I provide curved levers K, pivoted at K to arms B, the free or forward ends of these levers being provided with supporting-springs K and steady-pins K Blocks G are provided with laterallyprojecting wrists, 011 which are respectively journaled rollers G These rollers travel on levers K and hold the inking-rollers against the inking-plates during the lower movement of these parts.

Guide-plates I are made fast to the respective ends of the bed B, these guide-plates bein g of the form shown to guide the inkingrolls in their passage between the ink-plate and form. The rear portion of plates I are utilized in mounting the ink-fountain and distributing-rolls. The ink-fountain in the main is like ordinary ink-fountains in that there is an ink-container, I, and feed-roller 1 with the necessary mechanism for regulating the amount of ink that roller I feeds from the fountain. The fountain has depending arms 1 pivoted at I to plates 1. Connected, preferably, with one arm, I, is a rearwardly-projecting arm 1 that extends over shaft H. The rear end of arm I is provided with roller 1, the latter resting on cam h of shaft H, as shown in Fig. 1.

The top face of the cam h is substantially a flat surface, so that with the oscillation of the shaft H the cam h in its movement from a horizontal position of face in either direction will tilt arm I upward, and consequently will tilt the ink-fountain forward, the gravity of arm I being sufficient to return the ink-fountain rearward. Pawl z" is pivoted at i to the adjacent plate I. This pawl engages a ratchet-wheel, i, and the latter being made fast to a trunnion of the feed-roll, with each rearwardv movement of the fountain the pawl engages and actuates the ratchet-wheel and feed-roll. With each forward movement of the inkfountain the feed-r0111 comes in contact with distributing-roll J and deposits ink along a narrow strip lengthwise of this roller. The plates 1 are provided with slots 1 and I 111 the central slot, 1 is journaled the trunnion of roller J, with blocks 2' integral with caps 2' backing the trunnions. Frames J fit loosely in slot 1 so that the frames may reciprocate endwise therein, the frames being held in their respective slots by means of cap 2' aforesaid. In each frame J is journaled a distributing-roller, J For reciprocating these latter rollers endwise to give a better distribution of ink on theinking-plate, I provide inclines g and g on the inner faces of the roller-frames G. The arrangement of these inclines is shown more clearly in Fig. 2, these inclines being curved concentric with the axis of the roller-frame, the zero-point of the respective inclines being at g and the highest point being respectively at g and the opposing inclines of the two roller-frames being set in reverse order.

Lugs on the end of one frame J are arranged to engage inclines g and lugs on the IIO other frame J are arranged to engage inclines g By means of these inclines and of the oscillations of the roller-frame the two rollers shaft M J are reciprocated endwise, and the two rollers always move in opposite directions. The inking-plate E, as it sweeps past, engages and rot-ates these distributing-rolls, resulting in a thorough distribution of ink upon the plate.

Chase-hook e is secured by bolt 6 to the top side of the bed, the bolt serving also as a fulcrum for the hook. Plate 6 is pivoted on bolt 6, so that the plate may turn laterally. The plate has an incline, a that engages the under side of the rear portion of the chasehook. By turning plate e in the one direction or the other the rear en d of the chase-hook is elevated or depressed to tighten or loosen the hook end on the chase, steady-pins e (see Fig. 4.) serving to hold the chase-hook in place laterally.

Link II is pivoted at h to the adjacent side frame, A. This link is provided with longitudinal slot H and with wrist H, the latter connecting with pitman H for operating the latter. 1n slot H operates the sliding box 7L2, the latter connecting with wrist 7L3, that projects laterally from gear A". As gear A makes a half-revolution for each stroke of the bed, it follows that the inking-roll and inkingplate are moved from one terminus to the other with one stroke of the bed, and are returned to the starting-point with the next stroke of the bed, the inking-plate and inking-rollers, as already explained, always moving in opposite directions and overlapping at either terminus.

If instead of feeding sheets of paper by hand to the platen it is desired to feed the paper from rolls, grippers (Z and, for instance, link 0 are removed, leaving the platen stationary in its depressed position. Table (l is also removed. Next frame A placed in the position shown in Figs. 1 and 2, is secured as aforesaid. To one of wrists F of the crankshaft, and outside of pitman F, is secured crank-arm L, the latter having attached wrist L, and with this wrist are connected the rack-bars L and L \Vrist L is radially adjustable in slot L of arm L to give the desired throw to this crank. The teeth of rackbar L engage the teeth of pinion M of the This rack-bar slides through a chamber made in yoke M, and the latter being pivoted on shaft M the rack-bar is always held in the proper position relative to pinion M, so that the teeth of the rack-bar and pinion are always in mesh. On shaft M is keyed fast a pinion, M engaging pinion m, the latter being mounted on shaft m of feed-roller m The roll of paper M is mounted on a spindle, M and the latter operates in vertical slots M of standard M by means of which the roll of paper rests on roller m and the length of paper discharged from the roll for each stroke of the machine will depend on the movement of roller m regardless of the size of the paper-roll. By adjusting wrist L in slot L the desired movement is transmitted to roller m and to prevent this roller from reversing with the return-stroke of rackbar L the engaging gears M and m are thrown out of mesh during such return-stroke. The mechanism for accomplishing this is as follows: Next inside of the respective side pieces of frame A are located rock-arms N, of the bell-crank variety, both of which are keyed fast to shaft N; also, a tie-rod, N extends from one rock-arm N to the other, so that the two rock-arms, tie-rod, and shaft form a rigid frame-work. About midway of tie-rod N is attached a link, N, for actuating rock-arm N. 011 shaft N are mounted loosely short upright arms 91, located next inside of the respective rock-arms. The upright short arms n of rock-arms N have laterally-projecting lugs N, (see Fig. 11,) that overlap arms 72 and the latter and these lugs are re spectively connected by means of securingbolts n and adj HS'Llllg-SCTGWS M, by means of which arm n can be accurately adjusted toward or from lugs N and such adjustment having been made, arms at swing with rockarms N 011 a common axial line. Near the upper ends of arms at is journaled the aforesaid shaft M and by tilting rock-arm N gears M and m are thrown in and out of mesh. During the downstroke of rack-bar L gears M and m are in mesh, and the paper is passed 01f the roll and onto the platen. During the upstroke of rack-bar L rock-arms N are in their depressed positions, and gears M and m are consequently out of mesh, and feed-roll mt and the paper remain at rest. For tilting rock-arms N, the following is provided: Link N connects at n wit-h lever n", the latter being fulcrumed on tie-bar a of frame The rear end of lever n is provided with roller n, and the latter travels on cam f of crank-shaft F. During the downstroke of rack bar L lever 01; and the connected rock-arm N are held elevated by cam f holding gears M and m in mesh. During the upstroke of rack-bar L roller a by gravity of the connected parts, travels on the reduced side of cam f, whereby rock-arms N assume their depressed position, separating gears M and m. Adjusting-screws n bear against small metal plates 01, and these plates are backed by blocks of rubber, 11", secured in the corresponding pockets of lugs N. If, in throwing gears M and m in mesh opposing teeth should engage the ends of each other, rubber blocks 71, would be depressed, and no harm would accrue; also, an arm, N Fig. 11, is connected with one of arms n, so as to reach under gear m.

Arm N has a longitudinal slot, through which the securing-bolt passes that secures the tooth r". This tooth fits between the teeth of gear m, and tooth N is adjusted on arm N so as to enter' between the teeth of the gear on just as the two gears are separated, so that tooth N serves as a brake to hold gear on in proper position for the teeth thereof to receive in mesh the teeth of gear M when the latter is again moved forward.

Feed-rollerm at one end thereof, is provided with gear m that by means of intermediate gears, m transmits motion to gear O, which latter engages gear 0. These latter gears are mounted, respectively, on the shafts of the feed-rollers P and P, between'which the paper passes as the latter is fed along toward the platen. The lower roller, P, is of considerable length, and has a series of circumferential grooves, P in which operate fingers P, that prevent the paper from winding on the roll. These fingers are attached to crossbar P, that in turn is secured to the supporting-frame A The upper feed-roll, P, has a narrow and preferably crowning face, and is located about midway lengthwise of the roller P. On the same shaft are mounted rollers or disks 13, a trifle less in diameter than roller P, so that rollers 19 do not act as feed-rolls, but only to smooth down torn edges of the paper. Rolls 19 are secured to the shaft by set-screws, and are therefore adjustable lengthwise of the shaft, and are usually adjusted to travel near the edge of the paper. Plate 0 has a pintle, 0, that rests innotches 0 thus forming a pivotal hearing or hinge for the plate 0. The forward end of this plate rests on the roll of paper underneath the paper that is being paid off from the roll and prevents such loose paper from sagging.

On plate 0 are adjustably secured guides 0 that keep the paper in line. The rear or free ends of rock-arms N are connected by cross-bar N the latter having a longitudinal slot, N in which operate bolts N, for securing grippers N to hold the paper down on the platen during and shortly after the time theimpression is being taken, these grippers, of course, being elevated and depressed by the movements of rock-arms N. For severing the paper into sheets after the printing is done I provide the following:

On shaft a and on the end thereof opposite gear A is mounted bevel-gear a this latter gear engaging a bevel-pinion, Q, mounted on shaft Q, the latter, of course, running lengthwise of the machine. This shaft is j ournaled in boxes a, connected with frame A The rear end of shaft Q is provided with crankdisk Q the wrist of which operates in slot R of the movable shear-blade B. This blade is pivoted at r to the stationary blade R Rack-bar L engages pinion S, the rackbar reciprocating through yoke S, arranged substantially the same as the yoke just described with rack-bar L Pinion S is mounted on shaft S on which 'shaft is mounted the lower feed-roll, S this shaft bearing also gear S that engages pinion S on shaft 5".

Shaft S is mounted on levers s, and has mounted thereon the upper feed-roll, s, of the pair. This upper feed-roll consists of two narrow-faced wheels adj ustably secured on shaft S by set-screws, this roll being adapted to bear upon the unprinted margin of the paper. Levers s are pivoted on rod a on the frame A and the gravity of these levers and When rackof gears Stand S", but enough to remove the pressure from the paper. Fulcrumed also on rod a and lying side by side with lever s, are long levers the forward ends of which are connected by links 5 with wrists a The rear ends of levers s are connected by crossbar 3 over which cross-bar the paper passes. Tie-rod 5- extends from one lever s to the other, this rod being screw-threaded from end to end, and on this tie-rod are mounted thimbles s, the same being threaded internally for engaging the screw-thread of the tie-rod, whereby these thimbles are adjustable lengthwise of the rod, and are made to register with the respective margins of the printed paper. When by the down movement of lever 07, the forward ends of levers s are depressed, and in consequence thereof the rear ends of these levers are elevated, cross-bar s presses the paper up against thimble .9 thus clamping the thimble, after which the further upward movement of cross-bar s elevates levers s and the upper feed-roll, but, as aforesaid, does not throw gears S and S quite out of mesh, and this occurs just as the rearward movement of rack bar L commences, so that during the reverse movement of these feedrolls they are notonly separated some distance, but the paper meantime remains clamped on cross-bar 5 close to the feedroller, and by the upward movement of crossbar 8 the paperwill have been raised so that it could hardly, if at all, press upon the lower feed-roll, and consequently the rear movement of the rack-bar does not affect the paper.

Cross-bar A a section of which is shown in Fig. 2, rests upon a member of frame A This bar has a longitudinal 'slot, through which the securing-bolts pass for holding guides A, the latter being adjusted on either side of the paper. The paper, after it leaves the platen, is placed by hand between the lower feed-rolls and drawn along until in the position to be severed by the shears, the press being usually stopped for this purpose. As the distance from the platen to the shears is not always a multiple of the lengths into which the paper is to be out, more or less slack paper is allowed between the platen and the-lower feed-roll.

It is desirable to have some means of adj usting the throw of the lower feed-rolls independent of the upper feed-rolls, and this I accomplish by means of a slip-joint on rackbar L The arrangement of parts is purposely such that the lower feed-rolls will feed somewhat faster than the upper feed-rolls,

IIO

provided the slip-joint of the raek-bar l." were held rigid, and the lost motion at the slipjoint is adjusted to reduce and regulate the feed of the lower rolls as required. The rackbar L is connected with a wrist-block, Z, the latter having a channel, Z, on the inner face thereof, through which the rack-bar may slide endwise. The forward end of this rack-bar has a head, If, the same having a hole through which stud Z may slide easily. This stud is screwed into and remains stationary in the wrist-block 7-, and the outer end protrudes through head L some distance and is provided with jam-nuts Z. These j am-nuts are set to give the lost motion necessary in regulating the feed of the lower rolls. l'Vith such construction it is evident that wrist-block Z willmovc forward until it strikes head L before moving the rack-bar L forward, and on the return-stroke the wrist-block will have moved rearward until the jam-nuts strike L before moving the rack-bar rearward. In other words, the lost motion of the slip-joint is first taken up before the rack-bar is actuated in either direction. Raclcbar If has therefore an end movement equal to the throw of wrist L less the lost motion of the slip-joint. lVrist L having been adjusted to regulate the feed of the upper rolls, the lost motion of the slip-joint is by means of the jam-nuts adjusted to regulate the feed of the lower feed-rolls.

T is a register of ordinary construction for keeping account of the printed sheets of paper. This register is suitably secured to the pressframe, and is actuated by means of rod T, the hook end T of this rod striking pin T of the register. Rod T is connected wi h arm b of shaft 1)", the latter, it will be remembered, forming a part of the impression throw-off mechanism and oscillating with the press-bed and its supports. hen, therefore, arm Z) in moving rearward and downward, as it would have to do in avoiding an impression,rod T is moved rearward and downward, so that it does not strike pin T and consequently the register is not actuated while the impression throw-off is operated, by reason of which only the printed sheets are counted. The forward-and-rearward movement of arms B, that carry shaft Z)" and arm b is sufficient to give the requisite end motion to rod T for actuating the register. The severed sheets of paper fall upon an inclined table, 0", the latter having a foot-board, r adjustable up and down the inclined face of the table, according to the size of the severed sheets.

The train of gearing shown at the upper left-hand corner outside the frame in Fig. i is in Fig. 2 shown inside the frame. Either location will answer the purpose.
